The method involves protecting a value associated with a reference system by memorizing a data couple and by constituting and memorizing a table, and executing software related to a parameter from a parameter group which is associated with the reference system. An implementation of a computer program and accessing of data are carried out by executing the software. The protection of the value is made in a relation with a single part of the parameter from the parameter group and with sub-assemblies of the parameter group which includes the number of parameters higher than a determined value.; Independent claims are also included for the following: (1) a reference system comprising a protection unit for protecting a value associated with the reference system (2) a computer program product comprising instructions for implementing a computer program and/or data reference system coupling method (3) a method for verifying a current system (4) a current system comprising a unit for finding a value from a parameter from a group parameter (5) a computer program product comprising instructions for implementing a current system verifying method.
